CANNERJ Specification ofLetters Patent.

Patented Apr. 15,11913a Application filed May 12, 1910. Serial No..560,918.

To all whom itvm ay concern: I

Be it knowmthat I, Jn'rrmolfiLoss a citizen of the United States,and\resident of St; Peter, Nicollet county,State of Minnesota, have invented certain i new and usefuli Imw.

vessels,and more "especially to that class:

thereof known as steamers; and the object of the same is to produce an improved outfit for canning in a small way, the same contemplating either the use of its own:casing forminga furnace or the use of an ordinary stove or other source of heat.

To this end themventloniconsists 1n the details more fully described below andamply illustrated in the drawings, wherein.

Figure 1 is a vertical section of the proc ess kettle seated on a stove top, showinga flat'cover secured thereombycatches; Fig. 2 is a perspective detailishowing the bottom of the can holder as viewed fromibeneath.

In the accompanying drawings the improved process kettle has been indicated at K with the caniholder therein, the said. kettle being seated over an opening in the top of an ordinarystove S although? it, is to be understood that the kettle may be heated in any other manner desired.

The kettle K is a cylindrical vessel having a body 20 and an integral closed bottom 21 and an outstanclingrib or bead 22 struckin its body around and just .below its upper end; and within this kettle is loosely fitted the can holder indicated generally at 23 and which also comprises: a cylindrical body 24: smaller than that of the kettle so as to leave an annular space 25between them, and a flat bottom 26 provided with acentralhole 27 and on its exterior with a seriesof ribs 28 spaced from each other and radiating.

able points a gage 31, a safety valve 32 land a thermometer 33. The gage and the safety valve have only been shown generally inas-a much as theyconstitute no. part of the PI8S-1 6O ent invention. By preference it has a de-: pending skirt 34 surrounding its periphery and fittingclosely uponthe upper end. of

the kettle above the head 22.

The latch or other fastening device L;may be of any suitabletype.

By utilizing ribs 28 whichiextend radially from the central opening 27, separate passages are provided through which liquid is free to circulate.radially tothe space he tween the walls of the kettle and the can holder, the i direction of circulation being indicated by arrows in the drawings.

In the use of this device the parts are as-' sembled by grasping the bail 29 and lower: ing, the can holder 23 into the kettle untill its ribs rest upon the bottom thereof; then the kettle is placed directly upon the stove. The cover C. is applied in a manner which will beclear, and latched or looked upon 0 3 the top of the kettle to close it, the bail or. handle 29 being turned downward. It will. not be necessary to elaborate upon the proc-. ess of canning or cooking further than to say that whatever is to be steamed is placed 3 within; the can holder 23, possibly upon 1 shelves whichmay be supported by annular flanges 100 therein, or in a frame for carrya ing the cans if the devicebe large enoughto containseveral. Water is poured into this holder and both the holder and the space 25 thus become filled to the desired height; and the kettle and can holder placed upona 'stoveS.

The heat communicated to the bottom of the kettle soon boils the Water under the. holder and at. the lower end of the annular space 25, and the steam generated in; said.

s ace rises therein until it strikes the cover uponnvhich it condenses and falls back.

onto the cans or other articles within the a holder 28, so that a circulation of hot Water and steam is constantly maintained as shown;

by the arrows. Tlhe interior temperature a can be seen by the thermometer and the 105 pressure of the steam by the gage, and should the heat be such as to cause such pressure to rise to a dangerous degree the safety valve will open and afford relief. The parts are preferably entirely of metal and the kettle and holder should be of galvanized metal so as to prevent rusting. The parts may Well be of sheet iron and the cover of sheet inner vessel spaced from the outer vessel to permitthe circulation fthe fluid contents thereof; said inner Vessel. having an open top, there being a central hole in thebottom of the inner vessel, and ribs radiating from said hole and bearing onthe bottom ofthe outer vessel, flanges Within the-inner vessel,

and a cover closing the top of the outer vesi sell 7 2. process kettle for steamingor canning, comprisingthe kettle proper consisting; of a cylindrical vessel open at its top and-having a flat closedgbottom, a can holder therein consisting'ofa cylindrical body'anda flat bottom'having -a hole at its center,the

top disposed beneath the top of the kettle, spacing ribs secured to the bottom of said body and radiating from the hole therein to points close to the periphery of the bottom, flanges secured Within said body, and a cover for c-losi'ng the top of the kettle above the top of the holder.

'ni'ng, comprising an. outer vessel, a smaller inner vessel spaced; from the; outer vessel to thereof, said! inner vessel having,- an, open top, there being a central. 110182 in the ibote passages therebetween.
